SPECIFICATION forming part of ALetters'. Patent No. 530,705, dated December 11, 1894. Application filed April 27, 1894- Serial No. 509,280. (No model.)

To @ZZ whom it may concern:

Be `it known that I, EDWIN G. MUMMERY, a citizen of the United States, residing at 'Detroit, county of Wayne, State of Michigan, have invented a certainv new and useful Improvement in Vapor-Burners; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specication.

My invention relates to certain new and useful improvements in vapor burners, and consists of the construction, combinationand arrangement of devices and appliances hereinafter specified and claimed, and illustrated vin the accompanying drawings, in which-'- Figure 1 is a view in perspective illustrating my invention. Fig. 2 is a vertical sectiony on the line 2 2, Fig. 1. Fig. 3 is a vertical section on the line 3 3, Fig. l. Fig. 4. is a plan View of the bottom plate.

The purpose of my invention is to provide a vapor burner of superior eiciency, economy and utility, and I carry out my invention as follows: ,y

A represents the base or lower plate of the burner. This base or plate is made solid, admittin g no air therethrough. Itis constructed with a series of channels a, which in the drawings are shown extending parallel one with another across the p1ate,the transverse channels d all communicating with an outer channel a at the edge of the plate. The plate is formed with an exterior upwardly extended flange a2 and with a series of corrugations c2 forming between them the channels a.

B is a feed pipe, through which gasoline or other suitable liquid fuel is fed into the channel plate A. It will be perceived that as the fuel enters through the pipe B it will be distributed throughout the channels a. and a of the plate A.

Extending upward at each side of each of the channels a 2 is an airinlet plate C, forming a combination chamber D above each of the channels a of the base plate.

I have shown in the drawings my improved burner constructed of annular form, although Ido not limit myself to any definite shape. As so formed, the various chambers D Iare elongated, and communicate with the corresponding channels a beneath, and with the-exterior at their upper ends.

Above the annular channel a', I locate a covering plate A2. At the upper ends of the air inlet plates C, I engage a top plate E constructed with a depending flange E', the plate E extending about the air mixing plates, as shown. Thelange E depends from the outer edge of -the plate E toward theplate A2 but but stopping short thereof, the space between the lower edge of the flange E and the plate A2 being open, as indicated in the drawins. By thisconstruction air is readily admitted. betweenthe iange yE and the plate A2 so as to pass through the air inlet plates C into the chamber D.

Above the plate E, and over the bodyof the burner is a plate F constructed with a series of elongated slots f corresponding to the chambers D therebeneath, through which the name is emitted. The plate F is spaced from the plate E and made open at the side thereof for the admission of air to the. llame or vapor above lthe chambers D. The plate E is provided with a series of transverse bars e between the chambers D. This construction forms air chambers G between the vapor chambers D.

The chambers G are closed at the base and at the top, but air is admitted thereinto at the sides of the burner, the air passing from the chambers G through the adjacent air inlet plates C into the adjacent vapor chambers D.

, The air inlet plates C vmay be constructed in any suitable manner to allow the air to pass therethrough. Forexample, the plates C might be constructed in the nature of perforated walls, but I prefer that they should be constructed of cast metal, kerfed on their elongated sides so that there shall bea series of continuous or elongated air passages through which the air may pass into the vapor chambers D.` These elongated kerfs are more clearly shown in Fig. 3, as at 0. The

plates E, A2, and the base plate A are all united together in any suitable manner, as by bolts H, the various plates being preferably ICO formed with suitable ears for the engagement of said bolts with their corresponding plates.

The apparatus above described is complete in itself as a gasoline burner. Should it be desired, however, to employ kerosene, or any other heavier hydrocarbon fuel, my invention contemplates locating beneath the base plate A an auxiliary heater J of any suitable description.

As shown, the auxiliary heater consists of a base J formed with upwardly projecting annular flanges J2 and J 3, the one within the other, forming a channel J4 into which the fuel is admitted through an auxiliary feed pipe B communicating with the feed pipe B and provided with a controlling valve b. Within the flange J 3 the plate J is open to permit the passage of' air therethrough, centrally of the heater. Toward the upper end the flange J2 is kerfed, as shown at j to admit the air therethrough. The flange J2 extends upward above the inner flange J3. Above the central orifice J 5, above described, I locate a spreader K which may be held in place by a bolt 7a upon a transverse barj. It will be seen that the fuel flowing in to the channel J4 passes round about the inner flange J3. The spreader extends beyond the upper edge of the flange J3 and directs the air passing through the orifice J5 over the upper portion ol' the channel J4, by which it is more fully commingled with the vapors rising from the oil and with the products of combustion.

The iiange Eis spaced from the ends of the air mixers C, as shown, allowing the air to circulate therebetween. In Fig. 3 the plate F is omitted, as my invention contemplates either using or dispensing with said plate as may be desired. The kerfed flange J2 of the auxiliary burner may be provided with arib Q whereby the parts are united together.

In Fig. 1, the cover plate A2 is shown hinged to the flange a2 whereby when the bolts H are disengaged, the base plate A and the cover plate A2 may be readily separated or opened apart to give free access to the channels of the plate A should they need cleaning at any time. Instead of employing the bolts H, any

other fastening may be employed to hold the parts together. It is obvious from the construction of the auxiliary heater J, 'that pure combustion is effected thereby.

Especial attention is called moreover, to the fact that in the construction of the main burner, owing to the closed base plate A, and the entrance of air only from the sides through the air inlet plates C to support combustion, the heat has an upward tendency mainly, and no direct downward tendency as would be the case were the base plate A made open; but in this case the solid bottom prevents the heat from passing directly downward. It is obvious that in consequence a far greater degree of heat can be admitted above the burner than in the use of burners having an open base. Moreover, the draft of air being from the sides toward the center, the heat will not have much tendency to 'radiate outward. It is noticeable that there is here no delector above the burner to throw the heat downward.

While I have shown the channels a, ar-

ranged parallel one with another, extending across the base plate, l would have it understood that the channels might extend in other directions and be of dierent forms within the scope of my invention.

What- I claim as my invention is- In a vapor burner, the imperforate base provided with an outside channel a', and a series of inside channels a, communicating at their ends with the outside one; the plate A2, placed upon the top of the base and made to cover over the outside channel and provided with a slot or opening for each channel a; air inlet plates C, arranged upon the opposite edges of the slots and forming combustion chambers D and air chambers G, the flanged and slotted plate E forming a top for the combustion chambers, and the slotted plate F, raised above the plate E, so as to admit air to the flames, substantially as shown.

In testimony whereof I sign this specification in the presence of two witnesses.

EDWIN G. MUMMERY.
